Sub-shell /orbitals (Energy levels): The specific path of

  electron in a shell is called sub-shell. The maximum no. of




  electron that can be accommodate in different sub-shell are




  as below.



  The table below shows the sub-shell of a shell of an atom




  with their maximum no. of electrons.
